Access root file created by script Swift

Question

From this question: How can I get all image names in asset catalog group?

I want to access a file created in the root of an App in Swift.

My App is called Challenge and my script is

# Type a script or drag a script file from your workspace to insert its path.
#!/bin/sh
>./Challenge/fileNames.txt
for FILE in ./Challenge/Images.xcassets/actions/*; do
echo $FILE >> ./Challenge/fileNames.txt
done

I have tried

    let fileManager = FileManager.default
    let imagePath = Bundle.main.resourcePath! + "fileNames.txt"
    let imageNames = try! fileManager.contentsOfDirectory(atPath: imagePath)

And many other combinations .

This is not homework, I have tried various solutions but as I am not sure where the file is within the file system (how the root can be accessed within the App) I seem unable to locate the file.

Question: How to read ./Challenge/fileNames.txt from an App called challenger, created by a script during the build phase.

The file is located in the main bundle folder, not resource path:

let fileManager = FileManager.default
let imagePath = Bundle.main.path(forResource: "fileName", ofType: "txt")
let content = try! String(contentsOfFile: imagePath)

Returns nil? I can't believe that the script is wrong from the SO post... – WishIHadThreeGuns Mar 26 '19 at 07:49
Hmm. Frustratingly even with the edit I'm getting nil for the path – WishIHadThreeGuns Mar 26 '19 at 07:54
`contentsOfDirectory` applied to a **file** path makes no sense. – vadian Mar 26 '19 at 07:55
@WishIHadThreeGuns does the file in your project's Copy Bundle Resource section? – kubrick G Mar 26 '19 at 07:58
But what's the difference using path instead of resourcePath? Should that really matter using just path? – knoxgon Mar 26 '19 at 07:59
I don't know if it does the file other than it does in ./Challenge/fileNames.txt – WishIHadThreeGuns Mar 26 '19 at 08:03
@WishIHadThreeGuns could you look inside your app's package, see if the file did get added? you can find the package in your DerivedData folder: `~/Library/Developer/Xcode/DerivedData` – kubrick G Mar 26 '19 at 08:10
Doesn't look like it's there - so the script doesn't work? – WishIHadThreeGuns Mar 26 '19 at 08:14
@WishIHadThreeGuns yeah, i think it only copy file to your project folder, but Xcode only copy files in Copy Bundle Resource to your app. – kubrick G Mar 26 '19 at 08:17
@WishIHadThreeGuns or maybe it 's problem with the build setting order. does Run Script before or after Copy Bundle Resource? – kubrick G Mar 26 '19 at 08:21
